JOB STNTERING FINE ORES OR PULVEROUS ORES.

Application filed October 30, 1924, Serial No. 746,848, and in. seed}... August 22,1923.

.material to a distant discharge place can be efiected systematically in such manner that a practically continuous operation is secured.

The invention consists, 'chieflyin' a sintering system, comprising independent portable sintering vessels, exhausting apparatus, a plurality of work positions communicating with said exhausting apparatus and each adapted to receive a 'smtering vessel, a railway extending from'. the work positions to a distant discharge place for the sintered material, a char e preparing apparatus, a I f g device, and a second railway suplplorti'ng said charge filling device g between the charge preparing apparatus and the work'positions.

in the accompanying drawings,-Figure 1 1s a diagrammatic elevation of a plant for sintermg ores according to this invention,

Fig. 2 is a-diagrammatic top plan view of said plant, and Fig 3 is a diagrammatic cross section thereof. Figs. 4,. 5 and 6 are corresponding views of a modified plant.

With reference to Figs. 1-3, thenumeral 1 designates aj. charge reparing house tov which the materials to he sintered are carmeans of a railway 2, or: the like. Provi ed within the charging house are, preferably, a mingler 3 for preparing the mixture comprising fuel and fine ores which is to be'filled into the sintering vessels, a hopper 4 (Fig. 2) adapted to receive the material from the railway 2 and supply it to the mingler, and an elevator 4:1 or the like to lift the material from the min ler and supply it to another hopper 5 ig. 1). The charge preparing house is situated at one end of a platformfi comprising a series or row of work positions which extends along one side of an exhausting 'house'7. Leading from exhausters 9 within the house 7 to each of the work positions on the platform 6- is asuction pipe 8. While twoexhausters are shown in Fig. 2, it is to be noted that the number of the exhausters may be' chosen to answer to the requirements so that even every vessel may have its individual exhauster or section of an exhauster. Each work position is adapted to support a portable sinter'ing vessel 10, preferably in the shape of a tiltable receptacle having supporting armsof any appropriate type.

Provided at about the level; of the npper on the platform is arailway 11 extending edge of the sinteringvessels when standing over the 'platformand at a still higher level,

a second railway 12 is provided. The railway 11 carries a movable charge filling rec ielptacle 13 as well as a-movableigniter 14. e charge filling receptacle 13 is open topped and shaped asfa funnel at its lower end and provided with any suitable type of removablebottom. The railway 12 carries a crane 15 with means for lifting and supporting a sintering vessel; The platform 6 with a corresponding part of the railway 12 is enclosed within a house 16. The railway 12 extends to an emptying place 17 (Fig. 1),

where there is a receiving device comprising a chute 18 having a sieve (not shown in the bottom and a hopper 19 below sai sieve. The hopper 19 is situated above a railway 20, and the chute 18 ends above another railway 21. Standing on the railways 20 and 21 are wagons 22 and 23, respectively.

The plant described operates as follows As soon as the sintering of the materialcontained in any vessel on the platform 6 is completed, said vessel is lifted by means of the crane 15 and carried u to the emptying place where it is emptie The sintered material now slides through the chute 18 down into the wagon 23, whereas any material not sintered', should there be such ma-,

' terial, will pass the sieve to a large extent and drop down into the wagon 22.

emptied vessel is then restored by the crane 15 and put on-its place ;on-'the platform. While the emptying is taking place the charge filling receptacle 13 is carried up below the hopper 5 and filled with material to be sintered and immediately after the vessel is J 'ut downon its place-again, .the 'receptac e 13 is up above the vessel and the bottom"-tliereof opened so that the vessel will be filled with -material. The

freshmaterial thus supplied is then ignited by means of the igniter 14 toinitiate the sinteringf operation. The crane :15, having restored a vessel to its place, is immediately read to take a newvesssel, and as soon as the ling of a vessel is completed the charge filling receptacle .13 may again receive a fresh charge so as to be ready to'fill the next a v vessel emptied. The operation may thus continue without interruption.

The elevated railway 12 maybe replaced by a railway at one side of the platform 6,

and on this railway a separate wagon may,

be used having a platform into which a vessel with its sintered contents maybe displaced laterally from the platform 6, in

which case the vessels-may, preferably, be

provided with wheels.

With reference to Figs. 4-6 it is to be noted that the plant shown therein corresponds to that-described as regards the excharge hausterhouse 7 and its design,-the platform 6 with its work positions, the charge preparing house 1, and the railway 11 wlth the movable charge filling receptacle 13 and the movable igniter 14. V The plant shown in" Figs. 4-6 further comprises. a longitudinally movable travelling crane with its wagon 31 having means for lifting and carrying a sintering vessel 10. The house 16 also con -tains a railway 32 extending to an emptying place 17, which supports a wagon 33 adapte to carry a sintering vessel.

Said plant operates as follows: A vessel the contents of which is completely sintered is removed from its work position by means o:t-the wagon 31 and placed uponthe wagon" 33 whichthereupon carries the vessel u to the emptying place 17 where the vesse is -emptied. The'vessel emptied is carried by the wagon 33back into the house 16, liftedby means of the wagon 31 and again placed on its osition on the platform 6. Theing receptacle '13 filled in' the meantime is then carried up above the vestions each adapted to receive a sintering vessel, an individual suction pipe connecting each work position with saidexhausting apparatus, a railway extending from the work positions to a distant discharge place for the sintered material an d means movable on said railway and adapted to transport the vessels with the sinteredmaterial. from the work positions tothe, discharge place, a'charge'preparing apparatus, a sec ond railway extending between said charge preparing apparatus and the work 7 positions, and a charge filling apparatus? movable on the last mentioned railway, I "2.
